WINDOW FRAME AND SASHES.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed August 8, 1918. Serial No. 248,947.

' double sash windows, and to means for securing the windows in place adjustably and removably.

The main objects of the invention are to provide a window frame and sash members of improved form adapted for manipulation in such manner as to facilitate ready access to both sides of the window sections from the inside of the room, and having the usual appearance of two-sash windows; to provide sashes and fittings therefor of impro-ved form adapted for the usual up-and-down sash movements and also adapted for lowering and swinging forward successively; to provide for tilting or swinging the windows or sashes inward on bearings adjacent to their lower edges when lowered respectively for cleaning and repairing; to provide for so swinging either sash with the other sash remaining upright in its guideway; and to provide pivotal connections and guide means of improved form adapted to facilitate the operations herein described.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which Figure l is a front elevation of the inner side of a window frame and window in closed position, with the surrounding wall broken away. j j

Fig. 2 is a vertical section on the line 2 2 of Fig. l, the inwardly swung position prf the lower sash being indicated by dotted mes.

Fig. 3 is a vertical section on the line 2 2 of Fig. l with the upper sash lowered and the lower one raised, the inwardly swung position of the upper sash being indicated by dotted lines.

Fig. 4 is a horizontal section on the line 4- 4 of Fig. 2 with the sashes in normal closed position, the inwardly swung posilion of the lower sash being shown by dotted mes.

Fig. 5 is a horizontal section on the line 5 5 of Fig. 3, the position of the sashes being' reversed and the inward position of the upper sash being indicated by dotted lines.

Fig. 6 is an enlarged fragmentary section on the line 2 2 of Fig. l with the lower sash swung forward.

Fig. 7 is a similar view but with the sashes reversed and the upper sash lowered and swung forward.

5, with the lower sash raised and the upper one lowered as in Fig. 3.

In the illustrative embodiment shown in the accompanying drawings, the window frame l set in the wall 2 has an aperture 3 adapted to receive a pair of window sections or sashes 4 and 5, lower and upper respectively, each being adapted and arranged to slide past or into registry with the other for opening, either at the top or bottom, as usual in double sash windows.

Front and rear grooves or guideways 6 and 7 are provided on each side of the frame 1 wherein the sashes 4 and 5 are disposed and where they may slide respectively. Said guideways on each side are separated by a guide-rib or parting strip 8, the upper half 9 of which, corresponding with the upper sash 5, projects somewhat. farther into the window aperture than the lower half 10, corresponding with the lower sash. The lower or inner sash 4 is somewhat wider than the upper sash 5 and so coacts on its back side with the central guide strips 8 throughout its range of sliding movement, whereas the upper sash 5, being narrower, is engaged or held by said strips only when in its raised position, said sash being free to swing forward between the lower halves l0 of said strips when it is lowered. The part 9 extends down substantially iiush'with the upper sideof the lower rail 1l of the upper sash, which part l1 is formed with an ininto the inverted socket 18 in the lower end of the stop member 13. The lower end of member 14 is provided with a manually operable plunger 19 adapted and arranged to engage a downward aperture 20 at the foot of groove 15, whereby the strip 14 may be secured when said plunger is thrust down into its effective locking position. Said plunger is mounted slidably on the back side of strip 14 and is provided with a stud 19 having a head or handle 19". Said stud slides in a slot 14 in strip 14. An aperture 14 is formed in said strip to receive the plunger 19. Said stop 14 is preferably'A formed with a slight, permanent curvature so that when applied to the frame the lower end has to be sprung back into place to permit of thrusting the plunger 19 into socket 20, said stop being concave on its inner side 14a.

The lower end of the protruding part of strip `8 is cut away at 21 to receive the lower end of sash 4 when said sash is tilted n forward. By means of the resultant downwardly facing shoulder 22, the lower sash weights 23v secured to said sash by cords 23 are prevented from throwin u ward the lower part of the sash to whic t ey are attached as at 24 near the lower edge but spaced somewhat therefrom. The attachment at this point includes a plate 24 having a slot 24 with an enlarged lower end part 24" to admit the knotted end 23 of cord 23. A clearance space 25 is provided at each side of sash 4 to accommodate the cords 23 which extend edgewise of the sash stiles 4.

The cords 23 may hedetached from the sash 4 when the latter is swung forward,

i' by pullingv the sash forward and then s1iding the knotted ends 23 toward the foot of said sash and into registry with the large aperture 24 where the knots may be ejected and the cords so disconnected (see Fig. e.)

The upper sash 5 is supported by weights 27 secured to the cords 27 vwhich are connected to the sash through and by means of the rigid connectors 28 in the form of outwardly facing guide channels which are disposed at the sides of the sash stiles 5 and are pivoted thereto adjacent to their lower mule aq at 30. where the headed stud 30 on channel 28 fits in an aperture 30 back of la plate 30 on said stile 5. The head of stud 30 is disk-shaped and considerably larger in diameter than the shank of 'said stud, but is somewhat smaller than the round perforation therefor leadingto recesses 30 (see Fig. 9). Said channels extend upward nearly the whole length of stiles 5. They have their bases disposed normally fiat against the stiles 5 and serve to hold the lower edge of the sash in place and prevent same from swinging past the parting strip 8. Moreover, the guide channels 28 serve as filler blocks and prevent edgewise tilting of sash 5. When the sash 5 is lowered and vthe upper edge of the sash 5 is swung fortheir upper ends.

Each outer side strip or back stop 31 may be integral with the frame 1 and at its lower end is recessed at 32 to receive the lower tips of stiles 5 under the shoulders33,l so as to prevent lifting of the lower edge of Said sash by its cord weights when the sash is swung forward. Said sash 5 and channels 28 are detachable from each other 'by raising one side of said sash when tipped forward` and then removing stud'30 from aperture 30 by taking hold of bar 28 and manipulating same so as to remove studs 30 rfrom the recess 30. In order to raise one side as stated, the sash 5 must be pulled inward slightly so as to clear the shoulder 33, sufcient clearance for this being provided in grooves 7, where the channels 28 fit somewhat loosely. The relative up and down positions of the front and rear sashes is never fully reversed, that is to say, the inner sash 4 and outer sash 5 are n ever fully raised and lowered respectively at the same time, except when it is desired to release sash 5 for swinging forward.

Said frame 1 includes cord-ways or wells 36 for the several cords and weights, and each well is provided near thetop with a cordpulley 37. It is to be noted that the pulley stiles 37 are of uniform thickness throughout, and especially opposite both;` sashes, and that the filler channels 28 supplement the width of sash 5 to correspond to the width of sash 4. Extra clearance is provided at the top of the front guideway, as at 1, so as to give suiiicient head room to permit raising the front sash clear above the outer sash when the latter is lowered for swinging forward.

The operation of the front or lower sash is as follows: The window bein closed, the lower sash 4 is released by ,ralsing the plunger 19, and then upon Swingin the lower end ofthe stop 14 inward, sai stop may be withdrawn from its top engagement and so removed from the frame. The sash 4 is then swung inward at the top by grasping the top sash rail la and swinging same downward and inward, the lower sash rail and lower ends of stiles 4 being thrown back under the shoulders 22, and the adjacent parts of said stiles resting horizontally on the sill 38. By a reverse operation said sash et may be restored to its normal position and secured in place.

rlhe rear or upper sash is operated as follows: The front sash being in its raised or open position, the rear sash 5 is lowered. Said sash 5 is then swung forward by grasping the upper sash rail 5a and pulling the sash inward and downward to its horizontal position. By this movement the lower corners of the sash 5 are thrown under and into engagement with the shoulders 33, and the stiles 5 are disposed horizontally on the front sill 38. Said sash 5 may be restored to its normal closed position by a reverse operation, the sash being merely swung back and raised.

Although `but one speciiic embodiment of this invention is herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claim.

l claim:

A window frame having a vertical guideway, a removable sash slidable therein, lift means for said sash including a bar fitting loosely in said guideway with clearance at its front side, the lower end of said bar being turnably connected to said sash near its lower edge, said bar and sash having one a headed pivot and the other a retaining aperture for admission of the head of said pivot by movement in the plane of said sash, said trame having a downwardly facing rear shoulder and recess to receive the lower back corner of said sash when the latter' is tilted forward to prevent undue lifting, said sash and rod, when the former is tilted, being movable forward by reason of the lateral clearance of said rod in said guideway, suf iciently t-o clear said shoulder and permit raising alternately the sides of the sash at the pivotal end for disconnection of the pivot head from its aperture.

Signed at Chicago this 31st day of July 1918.
